Shell Script Loader is a framework (in a helper script) that can be used by shell-script-based applications for easy including or loading of co-shell-scripts or subscripts. With this utility, scripters may now be able to apply multi-file or module-oriented scripting or programming in shells just like the way they are always done in known languages like Perl, PHP, and Ruby. The provided functions are load(), include(), and call() with the extended versions loadx(), includex(), and callx(). The extended versions can accept glob patterns and regular expressions. Shell Script Loader supports many shells including the very old ones like bash, zsh, ksh, pdksh, sh, ash, dsh, and all shells based on the original sh. Scripts made with Shell Script Loader may also be compiled to form a single script. A generic compiler written in awk is already available.
sysfunc is a shell library intended for Unix sysadmins. It provides a set of portable shell functions including features such as file copy, symbolic link management, file/dir deletion, user/group management, data block replacement in a file, line replacement, commenting/uncommenting lines, service management, and volume group/logical volume/file system creation.
Qataki is a shell script that you can use to read/post notices from the command line in a simple manner. It supports Identi.ca, Twitter, and StatusNet. You can post, reply, retweet, or send direct messages; read personal, public, and user and group timelines (last statuses); read messages directed to you (i.e. where you are mentioned); read messages in context (conversations available only for Identi.ca/StatusNet); and search for notices.
repos-tools is a set of command-line utilities to make work on your code repositories faster and easier. It lets you push, pull, build, and do other things on your repositories all at once. The supported (D)VCSes are Git, Subersion, Bazaar, and Mercurial. For GitHub users, forking, following, watching, and dealing with issues can be done from the shell.
gcp (Goffi's CoPier) is a command line file copying tool, loosely inspired by cp, but with high level functionality like a progress indicator, the ability to continue copying multiple files even when there is a problem with one of them, and the use of a journal to track successful copying. File names can be fixed to ensure compatibility with the target filesystem. If you launch a copy operation when another is already running, the files are added to the first queue to avoid hard drive thrashing. You can keep track of files you have copied, and re-copy them later. gcp is approximately option-compatible with cp.
Tiny Life (tlife) is a simple Game of Life implementation designed to work as a filter for the shell, operating solely through standard input and output, with an emphasis on shell integration rather than pretty visuals. It supports customizable output and board sizes, custom rulesets, and random and user-specified seed values for the starting generation.
